What if we could determine if a given star is likely to host a planetary system like our own by breaking down its light into a single high-resolution spectrum and analyzing it? ... The dark bands result from specific chemical elements in the star s outer layer, like hydrogen or iron, absorbing specific frequencies of light. By carefully measuring the width of each dark band, astronomers can determine just how much hydrogen, iron, calcium, and other elements are present in a distant star. ...

11. CSPICE Routines: OSCELT_C
... Abstract Determine the set of osculating conic orbital elements that corresponds to the state (position, velocity) of a body at some epoch. ... In general, the elements found by this routine can have two kinds of problems: - The elements are not accurate but still represent the input state accurately. ... One recommended "sanity check" on the outputs is to supply them to the CSPICE routine conics_c and compare the resulting state vector with the one supplied to this routine. ...

13. http://www.mso.anu.edu.au/seminars/abstracts/20150804-1100.html
Some astronomers ignore low-mass stars because they aren t very bright. However, stars with initial masses between about 0.8 Msun and 8 Msun (AGB stars) play an important role as the main site of the slow neutron capture (s-)process, which produces roughly half of the elements heavier than iron. ... From this work, we will see have a better understanding of AGB nucleosynthesis, the chemical evolution of globular clusters, and the properties of helium-rich stars. ...

15. What is HISA?
... self-absorption - the absorption of light shining on an object by a process similar to that which produced the light originally; if a cloud emits less light than it absorbs from other clouds behind it, this net loss of light, termed self-absorption , causes the foreground cloud to appear darker than the background field (the term is from spectroscopy, where small absorption dips sometimes occur in larger emission lines, making the latter look as if it is absorbing part of itself) . ...
